美國人亦讚賞中國殲-20的側彈艙設計比F-22的更好
本帖最後由 MightyDragon 於 2013-3-29 08:18 PM 編輯難得的假期，當然要狂放文章，對中國各種各樣的先進技術成就加以讚揚 {:3:} 近來軍武版航空界的焦點除了中國要買二十四架蘇35S之外，當然就是殲二十在試飛時出現露出側彈艙內的彈彈的視頻、圖片等。對有部份崇拜洋人的人仕來說，洋人說一句話可抵得上中國人說十句，故此我亦不忘將此類文章貼出來「挾洋自重」一番 {:46:}

Original Title: The Chinese 5th Generation Fighter Has Some Truly Clever Engineering
In order to preserve their stealthiness and keep the RCS (Radar Cross Section) as low as possible, radar-evading planes rely on weapons bay: bombs and missiles to be fired are kept inside the bays until it’s time to use them.
For instance, the F-35 can carry one AIM-120D (AIM-120C8), on a trapeze : when needed, the BVR (Beyond Visual Range) missile is lowered into the airstream on the open bomb bay door, and ejected.
F-22 Raptors use canted trapeze to put the AIM-9 Sidewinder seeked into the airstream to achieve a lock on the target as the side bay doors are open.
Once the missile is fired, the bay doors close up.
Obviously, such method requires the stealth plane to fly with the open bay doors for a certain amount of time, a condition that can limit the aircraft performance, maneuverability, and increases the overall plane’s RCS, with a temporary exposure of the aircraft to the enemy radars.
Something that can be quite lethal in a Within Visual Range scenario.

The problem is to be partly solved with the use of missiles featuring the Lock On After Launch capability. With this kind of missile (available on the Raptor when the AIM-9M will be replaced by the AIM-9X Block II) the bay doors remain open just the time it is needed to eject the missile into the airstream.
However, China might have found a clever solution to the problem, as the latest images of the J-20 Mighty Dragon stealth fighter jet, emerging from the Chinese Internet, seem to suggest.
Indeed, the second prototype of the aircraft features a missile deployment device on the side weapons bay which extracts the selected air-to-air missile and then closes the door to keep the reduced RCS.
Simpler and probably cheaper than the use of LOAL missiles, the J-20′s deployment device shows that Chinese engineers are not simply copying U.S. tech: if not improving it, they are at least troubleshooting some of the issues already faced by their American counterparts, with some clever ideas.
The missile launch rail was used to carry the PL-10 IR air-to-air missile during tests.

這新聞應該讓俄羅斯很傷感,曾幾何時需要靠中國一起對付邪惡的美帝,直到如今俄羅斯依然需要大量從中國(包含台灣...等)進口龐大民生物資,而中國只需要俄羅斯的金屬.天然氣..等資源.{:32:} 大陸的隱形戰機真的很不錯
但是最大的瓶頸就是
隱形戰機會迫切需要掛空空導彈
是滿大的一個隱憂的 利用別人的缺點來改善成自己的優點
這是很平常的做法吧<br><br><br><br><br><div></div> f-22 是美國20多年前所研發設計的 但沒想到現在被中國迎頭敢上了 美國人這是在要國會加軍費吧 這表示在資訊或技術(不管哪來的)的取得上
中國都不落人後
甚至在研發上人才也都很充足
雖說F-22是20年前首飛的
不過他們要設計J-20少說最快也是10餘年內的事
能找出F-22的罩門並解決真的很厲害 不知道老美會不會變更F-22側彈艙的設計
老美哪一款戰機不是改出ABCD版 這個裝置並不困難.跟相機閃光燈彈出來的原理沒差多少.不之到F22會不會也改過來<br><br><br><br><br><div></div> 下次可能變成中國戰機變型機器人了吧~那麼會改的話....f-22價錢和尖-20差多少啊.人家可是砸錢下重本.中國敢公布戰機造價嗎 璿云 發表於 2013-3-30 08:05 PM static/image/common/back.gif

是的技術上和相機閃光燈彈出來無大差別 {:3:}
相機的閃光燈只有幾厘米，而殲-20的格鬥彈的長度可是有接近三公尺 {:46:} 呵！發動機俄造的，不想多做解釋！{:31:} 技術方面應該也有精進吧~外國人是不是說客套話~等到真的實戰就知道了 本帖最後由 MightyDragon 於 2013-3-30 09:26 PM 編輯

呵！發動機俄造的，不想多做解釋！
對於一個大部份戰鬥機都是外購而來、小部份則是裝組外國配件(達96%以上)的地區這類說法只能是酸葡萄：全寫是「吃不到的葡萄是酸的」（來源：伊索寓言「The Fox and the Grapes」） {:3:}
殲-20用俄發？有何証據？還是只是人云亦云 {:46:}
